General description
3,4-Dihydroxybenzoic acid is a catabolite of epinephrine. It is a phenolic compound and an important constituent of lignin present in wine, green and black tea, and herbal medicines, which exhibits anti-inflammatory and antitumor promotion. 3,4-Dihydroxybenzoic acid is also a model matrix for ionization of peptides, proteins and carbohydrates in the MALDI (matrix-assisted laser desorption ionization mass spectroscopy) technique.
Application
3,4-Dihydroxybenzoic acid may be used as a reference standard for the determination of:
- Phenols in biomass pre-treatment hydrolysates by high-performance liquid chromatography method.
- 3,4-Dihydroxybenzoic acid in wine by high-performance liquid chromatography with a microbore column.
Biochem/physiol Actions
Chemopreventive in several animal models of carcinogenesis. Blocks cell proliferation in the post-initiation phase.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
